摘要： The present invention comprises a drum unit (7) provided with a drum tube (31) having a cylindrical shape. The drum tube (31) is formed with at least one opening (33) at one axial end thereof. A flange member (32) is configured to be inserted into the opening (33) in the drum tube (31). The flange member (32) is provided with a support hole (35) into which a shaft pin is inserted for supporting the drum tube (31) and flange member (32). An earth plate (40) is formed with projections or claws (44) that extend radially outward from a peripheral edge of the earth plate (40) such that the projections (44) contact with an inner peripheral surface of the drum tube (31). The earth plate (40) is also formed with a pair of contact pieces (49, 51) extending axially away from the earth plate (40) and also extending toward one another. The contact pieces (49, 51) are spaced apart from one another by a predetermined distance but are also configured to contact and engage a portion of the shaft pin.
